ESL One Katowice 2015 Cobblestone Souvenir Package

ESL One Katowice 2015 Cobblestone Souvenir Package is a Valve-designed case classified as a souvenir package and released on March 11th, 2015. It represents an event-tied container rather than a standard cosmetic sale item, aimed at collectors who follow tournament-origin pieces.

As a case, this item acts as a container players can open to receive souvenir in-game items. The basic mechanic is that the package sits in inventory until opened with the appropriate method, after which the contained cosmetic is granted to the holder.

Market-wise this package sits in the grail bracket, meaning it occupies the high end of the spectrum and moves under different conditions than budget or mid-tier containers. For a seller that translates to a different buyer profile and liquidity expectations compared with everyday cases.

This package was released on March 11th, 2015 and is tied to the ESL One Katowice 2015 event, which is central to its identity. That origin anchors its appeal and separates it from general rotation cases released outside event contexts.

Being a souvenir package, it yields souvenir items tied to event drops rather than generic stickers; it functions as a container for those souvenir cosmetics. As with weapon cases, opening standard cases requires a matching key, so buyers should be mindful of opening mechanics when handling containers.

Holders can cash out through Steam-authenticated checkout for instant USD settlement; the live market price is displayed on the page and reflects current demand. Use the price block on the item page to gauge the market before committing to a sale.

Collectors prize this package for its event provenance and Valve design, which combine with its grail-tier positioning to make it a candidate for long-term holding. Its value story is tied to origin and category appeal rather than routine drop frequency, so patience and timing matter for sellers and holders alike.
